The Required Spatial Resolution to Assess Imbalance using Plantar Pressure Mapping
arxiv(2024)
摘要
Roughly 1/3 of adults older than 65 fall each year, resulting in more than 3
million emergency room visits, thousands of deaths, and over $50 Billion in
direct costs. The Centers for Disease Control and Prevention (CDC) estimate
that 1/3 of falls are preventable with effective mitigation strategies,
particularly for imbalance. Therefore, quantification of imbalance is being
studied extensively in recent years. In this study we investigate the
feasibility of plantar pressure mapping in balance assessment through a healthy
human subject study. We used an in-house plantar pressure mapping device with
high precision based on Frustrated Total Internal Reflection to measure
subjects sway during the Romberg test. Through the measurements obtained from
all subjects, we measured the minimum spatial resolution required for plantar
pressure mapping devices in assessment of balance. We conclude that most of the
current devices in the market lack the requirements for imbalance measurements.
